I suggest the vocabulary release notes contain changes for when a non-standard concept_id maps to a new vocabulary, so we can be sure to download the new vocabulary from Athena. Currently, the release notes only contain domain changes.
Example:
concept_id = 46257533 in the CPT4 vocabulary now Maps to concept_id = 35945494 in the OMOP Genomic vocabulary. We don’t have the OMOP Genomic vocabulary in our CDM, therefore, we need to download it from Athena, so concept_id = 46257533 will map to 35945494 instead of 0. If the release notes notified vocabulary users of this change, then we could add this to our list of Vocabularies to download from Athena before we update our ETL
